IMPROVEMENT IN PLOWS.

Specification forming part of Letters Patent- No. 46.454, dated February21, 1865.

To all whom it may concern;

Be it known that I, JOHN DEERE, of Moline, Rock Island county, State ofIllinois, have invented an Iniprovementin Landside and Share Plates forPlows and I do hereby declare that the following is a full, clear-,andexact descrip- Lion thereof, reference being had to the accompanyingdrawings, making a part of this speci fication, in which- Figure l is aside elevation of the landside of my improved plow. Fig. 2 shows theopposite side of Fig. 1. Fig. 3 is a side elevation, showing the insideof the landside-plate and standard attached to it. Fig. 4 is aperspective view of Fig. 3. Fig. 5 is a bottom view ofthe plow. Fig. 6isa perspective view of the plowshare.

Similar letters of reference indicate corresponding parts in the severalfigures.

This invention relates to improvements'iu plows which have theirshare-plates, moldboards, and landsideplates formed separately andafterward bolted together.

The object of my invention is to provide for securing the standard of aplow to the inside surface of the mold-board in afirtner and moredurable manner than hitherto, and at the same time to provide forreadily detaching these parts at pleasure, as will be hereinafterdescribed.

Another object of my invention is to provide for securing together thelandside,1noldboard, and share, so that in the event of any one of theseparts wearing out or breaking they may be replaced by other parts of asimilar form and construction, as will be hereinafter described.

To enable others skilled in the art to make and use my invention, 1 willdescribe its construction and operation.

In the accompan yingdrawin gs, A represents the landside-plate, which isconstructed with an overlapping pointed portion, a, an elevated guard,I), and a narrow heel-piece, c, as shown in the enlarged views, Figs. 3,4, and 5. In forming this plate A, I provide for attaching to it thestandard B, share 0, and mold-board D, all of which may be constructedessentially in the usual manner, so far as their form is concerned. Thisis done in the following manner: The ear 5 is cast with-thelandside andlocated at the forward edge, and at or near the upper end of theelevated portion or guard 12. This car or lug is perforated to receivethe bolt which secures the mold-board to it, and it is arranged orinclined in such manner as to allow the mold-board to fit snugly upon itwhen the latter is secured in its place on the landside. This car 5serves as the upper support and bearing for the mold-board, which latteris further secured by means of a lug which is cast on the inside of theshare-plate (l, as will be hereinafter explained.

Three lugs or projections, 3 3" 3, are cast on the inside surface of thelandside A, and arranged as shown in Figs.3 and 4. These three lugs areintended to serve as supports and stays for the lower part of thestandard B. Thelowermost lug, 3", supports this standard, and the twolugs against which the vertical edges of the standard abut serve asguides for adjusting it in place, and also stays for relieving the twofastening-bolts e e from undue strain in a longitudinaldirectiou.Ifdesirable, another lug, 3, may be cast on the plate A, as shown inFig. 4, just below the upper lug, 3. While these lugs 3 3 3 serve torelieve the strain from the fastening-bolts c e of the standard B, theyalso serve the important purpose of guides for determining the properposition for fastening the standard to its plate. The ear5alsoservesasimilar purposefor the moldboard. Thus it will be seen that in a singlesolid piece or castiugIprovide for giving great strength to thestandard, and for holding it rigidly in place, so that it cannot bedisplaced without actual breakage. Another advantage which I obtain bythis single casting A is that the standard is protected for aconsiderable distance above its lower end by the elevated portion orguard b, and hence dirt is prevented to a great extent from fallingthrough into the furrow. Besides this a smooth polished surface ispresented to the earth, which prevents it from sticking to the landsideand obstructing the movement of the plow through the soil.

The share 0 is constructed east with the usual vertical laudside-poiutand share-plate, which are adapted to fit the lower edge of themold-board and to receive the overlappiu g passage of the plow throughthe earth.
